EDISON — Vandals damaged six vehicles at an Edison Lexus dealership, scratching swastikas into the side of two cars and other graffiti into the other cars, police said.

Authorities alerted the Middlesex County Prosecutor's Office to the damage that was discovered when employees came to work at the Route 1 dealership Thursday morning, Lt. Salvatore Filannino said.

Tires were stolen off one of the two cars marked with swastikas, and that vehicle was left on blocks, Filannino said. He said that while the swastikas are being investigated as bias crimes, the other graffiti was not in that category.

The crime occurred sometime late Wednesday night or early Thursday morning, Filannino said.
